Is made of bauxite as the main raw material, in the furnace above 2200 degrees in the melting furnace by the reduction and made of brown artificial corundum, its texture dense, high hardness, high melting point, thermal conductivity, high temperature and stable volume, not easy turtle Crack, acid, alkaline good. The main chemical composition of corundum is AL2O3, its content is 94.5% -97%, and the other contains a small amount of Fe, Si, Ti and so on. Through crushing and shaping, magnetic separation to iron, sieving into a variety of particle size, product size according to international standards and national standards of production, but also according to user requirements granular processing. The general particle size is F4 ~ F320, and its chemical composition varies according to the size of grain. Outstanding features of the crystal size is small, impact resistance, due to self-grinding machine processing broken, the particles are mostly spherical particles, dry surface, easy to bind agent.

    Corundum is mainly used for abrasive abrasive abrasive, high standards of wear-resistant floor, water filtration and so on. Sandblasting abrasive Application: workpiece material, sandblasting the purpose of the process requirements; stainless steel, surface decontamination, in addition to welding slag and matte effect; iron parts, to rust, decontamination, in addition to oxide, Glass products, scrubbing, engraved patterns; plastic products (hardwood products) matte effect; denim and other special Fabric, plush processing and effect patterns. Also suitable for cast steel parts of the core sand, paint and investment casting shell material, and can be used as carbon steel, alloy steel, hard bronze, cast iron pieces of coarse grinding and free grinding abrasive.

    Customers choose our reasons:

1. Sandblasted corundum - sandblasting abrasive hardness is moderate, high bulk density, no free silica, than the major, good toughness, is the ideal "green" type sandblasting material, widely used in aluminum, copper profiles glass , Washed jeans, precision molds and other fields;

2. Free grinding - grinding grade abrasive, used in the picture tube, optical glass, monocrystalline silicon, lenses, watches with glass, crystal glass, jade and other fields of free grinding, is widely used in the domestic high-level grinding materials;

3. Resin abrasive - Abrasive with color suitable, good hardness, toughness, the appropriate type of grain cross-section and edge retention, used in resin abrasive

4. Coated abrasive - abrasive is sandpaper, gauze and other manufacturers of raw materials production;

5. Corundum functional filler - mainly used for automotive brake parts, special tires, special construction products and other collar can be used as the construction of highway pavement, aircraft runway, wharf, parking lot, industrial floor, sports venues and other wear-resistant materials ;

6. Filter media - is a new field of abrasive applications, the use of granular abrasive filter bed for the underlying media, purified drinking water or waste water, is a new type of domestic and foreign water filter material, especially for non-ferrous metal mineral processing, oil drilling mud aggravating agent.
